What is Powder Coating?

Powder coating is the process of applying electrostatically charged grounded particles of colour pigment and resin to a metal based product or part. The parts are then moved into an oven where they are heated for a period of time ranging from 10 to 20 minutes at an average of 200°C depending on the type of material and powder used. In the over, the pigment and resin begin to melt and form into one. Once cooled, it is one of the most durable paints available to protect your product.

Reference and precautions for powder coating construction:

1.Construction method: High-voltage electrostatic spraying or friction electrostaticspraying method is adopted for construction.High voltage electrostatic spraying process parameters:

Output voltage: 30-90KV

Input voltage: 220+10V

Distance between spray gun and workpiece: 100-300mm.Powder supply pressure: 0.5~2kg/cm

2. Pre-treatment of workpiece: the workpiece is degreased, derusted and phosphatizedby mechanical methods (shot blasting, sand blasting, etc,) or chemical methods, and thendried or dried after being cleaned by clean water. The quality of workpiece treatment has agreat influence on the coating quality, and improper treatment will cause the coating ofworkpiece to fall off, rust and blister.

3. The compressed air used by the spray gun must be purified by degreasing, dust removaland water removal, otherwise the coating quality will be affected.4. Bake the sprayed workpiece according to the specified time. lf the workpiece is large, thebaking time should be appropriately extended to ensure the coating quality.5. When replacing the powder, it must be cleaned up, otherwise there will be interference,causing loss of light, shrinkage cavity and miscellaneous spots.6. Ventilation equipment should be used in the spraying workshop to prevent explosion dueto excessive dust density.

7, the operator should wear dust-proof tools.

8. At the same time, it also provides professional and innovative solutions.
